The mobile network standardisation body 3GPP introduced two new features – PSM (Power Saving Mode) and eDRX (extended Discontinuous Reception) – minimising power consumption of IoT devices and extending their battery power up to ten years. In IoT applications such as container tracking, intelligent meters, or agriculture sensors, the devices do not need to send or receive data continuously.
Oliver Wruck, Director MNTS at Comprion, explains: “Being an important member of the mobile ecosystem, we felt the need to test the UICC interface for devices that support PSM and eDRX in order to prevent unpleasant surprises when the devices go live in mobile networks.”
